The definitions of "beautiful", "sexy" and “handsome” differ slightly between French and Korean people. I know that when Koreans use these words, they usually refer to physical beauty, such as "your eyes are beautiful" or "your nose is very high". However, it is not common to talk about physical beauty in France. When a French person says "you are beautiful!" or "you are sexy!" or "you are handsome!", it usually means that your heart is warm, that you are kind, or that you are smart.
